Question

can somebody do this

6x²-x-2=0

Answer 1

Answer:

X= 1 + 7/12

x = 1 - 7/12

Step-by-step explanation:

Answer 2

Answer:

$x=\frac{19}{12}\\ or\\x=\frac{5}{12}$

Step-by-step explanation:

$6x^2-x-2=0$

a=6

b=-1

c=-2

$x=-b\frac{+}{}\frac{\sqrt[]{b^2-4ac} }{2a}$

$x=-(-1)\frac{+}{}\frac{\sqrt[]{(-1)^2-4(6)(-2)} }{2(6)}$

$x=1\frac{+}{}\frac{\sqrt[]{1+48} }{12}$

$x=1\frac{+}{}\frac{\sqrt[]{49} }{12}$

$x=1\frac{+}{}\frac{7}{12}$

------------------------------

$x=1+\frac{7}{12}$

$x=1-\frac{7}{12}$

------------------------------

$1+\frac{7}{12}=\frac{(1*12)+(7*1)}{12} =\frac{12+7}{12} =\frac{19}{12}$

------------------------------

$1-\frac{7}{12}=\frac{(1*12)-(7*1)}{12} =\frac{12-7}{12} =\frac{5}{12}$
